Batt and roll insulation helps keep your home at a comfortable temperature, improves energy efficiency, and reduces noise transmission. The average batt and roll insulation cost is $0.80 to $2.60 per square foot.
That translates to $800 to $2,600 to insulate a 1,000-square-foot wall area. However, prices will vary depending on factors such as the home’s size, installation complexity, regional labor costs, and material type.
For this guide, we gathered data from big and small cities in the U.S., so you can get a good estimate of how much this project will cost in your area.
Cost by Location
Generally, you’re going to pay more in areas with higher costs of living that result in higher labor costs. Moreover, you may pay more for insulation if you live in a colder climate, since the layer of insulation has to be thicker to withstand extreme temperatures.
See the table below for a snapshot of the costs to install batt and roll insulation in a sample of cities across the country:
| City | Cost per square foot (including labor and materials) |
| Northeast U.S. | |
| Pawtucket, RI | $0.79 – $2.55 |
| New York, NY | $0.93 – $3.12 |
| Southeast U.S. | |
| Dothan, AL | $0.71 – $2.27 |
| Atlanta, GA | $0.73 – $2.34 |
| Midwest U.S. | |
| South Bend, IN | $0.81 – $2.64 |
| Chicago, IL | $0.86 – $2.84 |
| Northwest U.S. | |
| Corvallis, OR | $0.76 – $2.48 |
| Seattle, WA | $0.87 – $2.91 |
| Southwest U.S. | |
| Roswell, NM | $0.73 – $2.34 |
| San Diego, CA | $0.82 – $2.70 |
Cost Estimator by Size
Naturally, costs increase as the size of your project increases. The average installation costs $0.80 to $2.60 per square foot, including materials and labor.
You can use the following table to get an idea of the typical cost range of batt and roll insulation professionally installed for homes or rooms of different sizes:
| Project Size (Square Footage) | Typical Cost Range (Materials and labor) |
| 400 | $320 – $1,040 |
| 600 | $480 – $1,560 |
| 800 | $640 – $2,080 |
| 1,000 | $800 – $2,600 |
| 1,500 | $1,200 – $3,900 |
| 2,000 | $1,600 – $5,200 |
Labor Costs
You can expect to pay between $40 and $80 per hour for a contractor to install batt and roll insulation in your home. Costs will be higher if the pro needs to remove old insulation and if the area where the insulation needs to be installed is hard to reach.
Pro Cost vs. DIY Cost
You can install batts or rolls of insulation yourself if you want to save money. However, you need to be careful, as some of the materials involved can be skin irritants.
Plan to spend around $180 on tools and supplies, such as a stapler, caulk gun, caulk, and protective masks, if you don’t have any at home, plus the batt insulation itself. Batt insulation costs $0.10 to $2 per square foot for the materials, depending on the type and R-value.
However, hiring a pro will ensure the installation goes smoothly, with no gaps that compromise the insulation’s energy efficiency. So, if you’ve never done something like this before, it’s best to leave it to the pros.
Other Factors That Affect Cost
There are other factors you should take into account to estimate the costs of your project, including the following:
Insulation Material
Batt and roll insulation is made of flexible fibers such as fiberglass, mineral (rock and slag) wool, and natural fibers, such as cotton and sheep wool.
Fiberglass is typically the most common material used and also the least expensive, whereas cotton and wool are costlier.
- Fiberglass batt is made from glass fibers woven into a mat. It is relatively inexpensive, easy to install, and effective at preventing heat loss in the winter and heat gain in the summer. It is also non-flammable and does not absorb moisture, which can reduce the risk of mold growth.
- Mineral insulation, also known as rockwool insulation, is a type of insulation made from natural minerals such as rock, slag, or glass. Rock or mineral wool offers a better R-value than fiberglass.
- Natural fiber insulation is made of cotton, sheep’s wool, straw, wood fibers, and hemp. These materials are eco-friendly because they are renewable and biodegradable and have a lower environmental impact than synthetic insulation options. However, it can be more expensive than other insulation types.
Faced vs. Unfaced Insulation
You can choose between faced or unfaced batts. Faced insulation is a little more expensive. It comes with a paper facing that adheres to the wooden studs or joists and acts as a vapor barrier, preventing moisture from entering the building materials and causing mold or rot.
Unfaced insulation is best when expanding the attic insulation or adding soundproofing between floors or interior walls.
New vs. Existing Construction
It is cheaper to add insulation to new constructions because it is easier to install batt and roll insulation to unfinished wall cavities.
For previously insulated constructions, you should expect additional costs for tearing out the existing insulation. The cost to remove insulation ranges from $1 to $3 per square foot.
R-Values
R-value is used to measure the effectiveness of insulation materials. The higher the R-value, the better the material’s insulation performance, and the higher the cost. The most common R-value for both batt and roll insulation is between R-3 and R-4 per inch. Colder climates require a higher R-value to maintain the home’s temperature.
Household Area
Household insulation areas typically include the attic, walls, floors, crawl spaces, exterior walls, and foundations. Insulation in these areas can help maintain a comfortable home temperature year-round, reducing energy consumption and utility costs. However, depending on the household area to be insulated, prices will vary.
Usually, insulating attics and crawl spaces costs more because the insulation applied has to be thicker and have a higher R-value.
Ways to Save on Batt and Roll Insulation
Batt and roll insulation is already one of the most budget-friendly types, but there are still a few ways to cut costs even further, without sacrificing too much performance:
- Choose fiberglass insulation, which are typically less expensive than wool or cotton while still delivering reliable thermal protection.
- Opt for unfaced batts (without a built-in vapor barrier). They cost less than faced options.
- Install during the building or remodeling phase, which is much cheaper than opening up existing walls or ceiling later.
- Opt for lower R-values to cut on costs if you live in a temperate climate. This won’t work well if you live in a region with harsh winters.
FAQ
The lifespan of batt insulation depends on several factors, including the type of insulation, the quality of installation, and the environment in which it is installed. In general, most types of batt insulation can last for decades unless damaged.
Reflective and blow-in insulation are the cheapest insulation types. As for batt and roll insulation, fiberglass is the least expensive material to purchase and install.

Batt insulation and roll insulation look very similar and are equally effective at insulating a space, but the difference between them is that batt insulation comes in pre-cut lengths and widths, while insulation rolls, as the name suggests, is sold in large rolls.
Batt insulation comes in pre-cut panels that are easy to install. They are designed to fit between studs, joists, and other tight spaces. Roll insulation can be cut to fit any space, making it more versatile. Ultimately, the choice between batt and roll insulation depends on the specific needs of your project and your personal preferences.
